vention, such as will enable others skilled inthe artpto which it appertains to make and use the same.

operated window cleaners, designedfor use in cleaning the windows in front of the motorman on a street c ar, and one of the. principal objects of the invention is to provide a device for wiping oil' rain or snow from a window through which the motorman might look to see if the track is clear, and means whereby the window cleaner` may be operated through connections` from the air brakesystem of the car.

Another object of the invention is to provide a window cleaner adapted to be operated by means of a' cylinder and piston operatively connected to an air tank or through an air brake system of a car, and to provide means whereby the reciprocation oflthe piston carries a. window cleaner across the window pane from -top to bottom for wiping rain or snow oi the window, whenever required.

These and other objects may be attained by means of the construction illustrated in the accompanying drawings, in-whichf- Figure 1 is a front elevation ofa motor car showing a pneumatically operated window cleaner mounted thereon and made-in accordance with this invention,l Fig. is a vertical sectional (new through the cylinder and the guide tube for the cleaner, Fig. 3

is an enlarged sectional view taken on. the line 3-3 of Fig. 2, and'looking in the di- 'rectionindicated by the arrow, Fig. 4 is a front elevation of the pneumatically oper- L ated windbw cleaner removed from the car,

Fig. 5 is a sectional view and showing the manner of makin the connections at the top and bottom o the cylinder, said concleaner up or down', and Fig. 6 is a sectional viewv taken `on the line 6-6 of Fig.'4, look-f inein'the direction indicated by the arrow. ferring to the drawings, the numeral 1 vclearly in Fig. 5. p `The operation of the invention may be designates the front of an ordinary motor car and 2 is the front window through which the motorm'an usually. looks to see if the track is clear.

' ber is a vertical rod 7 mounted in a guide This invention relates to pneumatically` forms of window'cleaners or wipers may be utilized.

Communicating with the cylinder 3 near its upper end is a pipe 13 havinga vertical branch 14, which connects with the pipe 15 leadingto the air brake system, and a two-way valve 16 is provided with a stem 17 which can be operated to admit air' through the pipe 14 and .13into the cylinder 3, or which can be operatedto admit-'air through the pipe 18 into the cylinder 3 near the bottom thereof. The pipes 13 and 18 extend through the front o the car, as shown more briefly described as follows: When the lever orlstem 17 of the valve 16 is operated air is admitted through the vertical pipe 14 and through the pipe 13 -into the cylinder 3 near the top thereof to force'the piston head 5 downward and to thus carry the rod 7 downward and with it the window cleanerA which is in contact with the/window pane at the front of the, car.

For guiding the window cleaner 10 in its vertical movement, guide bars a may be connected t'o the opposite sides of the window pane, and the ends of the cleaner may be guided by,` these bars in any suitable manner.

It will be apparent from 'the foregoing that the invention is simple in construction, can be uickly applied to the front of the car, is e cient in operation, and inexpensive` to manufacture. While the device has been a piston rod, an arm carried by described in connection with a car Window, it will be obvious that it may be used for cleaning Windows in dwellings or apartment houses Without material change in the structure. Variouschanges may be made in the details of constructionvvithout departing from the spirit and scope of the invention as defined in the claims.

What is claimed is 1. A Window cleaner comprising a cylinder, a piston in said cylinder, a piston rod connected to said piston and provided with an angular arm, a rod connected to said arm, a guide tube in Which said rod is mounted, a Window .cleaner connected to said rod, and means for moving the piston up or down in the cylinder.

2. A pneumatically operated street car window cleaner, comprising a cylinder communicating with the source of compressed air, a. piston in said cylinder, a piston rod extending through the bottom of the cylinder, an arm connected to said piston rod, a rod connected to said arm, a guide tube in which said rod is mounted to reciprocate simultaneously with the piston, said tube having a longitudinal slot therein, a Window cleanerdconnected to said rod.

3. A pneumatically operated Window cleaner for street car windows, comprising a cylinder, a piston mounted in said cylinder, the piston rod, a rod carried .by the arm, a slotted guide tube, in which said rod is mounted, a Window cleaner 'connected to said rod, guides for said Window cleaner, and means for admitting compressed air near the opposite ends of said cylinder for reciprocating said plunger. L

4. In a pneumatically operated Window cleaner for street car Windows, the combination of a cylinder communicating with the air brake system of the car, a piston in said cylinder, a Window cleaner, guides orsaid window cleaner, and connections between the said piston and said cleaner to move the cleaner simultaneously with the piston for cleaning a window.

5. A pneumatically operated Window cleaner comprising a cylinder, a piston rod,

a piston in said cylinder, an arm connected to the piston rod and provided With a supporting rod disposed parallel to the piston rod, a slotted guide tube, a Window cleaner connected to said supporting rod, said Window cleaner compr1sing a tube having ak slot therein, a rubber Wiper connected to said tube, and guide bars at opposite sides of the Window for said Window cleaner.

In testimony whereof I aiiix my signature in presence of tWo Witnesses: f
